One frequently pulled in by the Met? (5-4)

I believe the answer is:

opera-goer

'one frequently' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'pulled in by the met?' is the wordplay.
'pulled in' becomes 'goer' (I can't justify this - if you can you should believe this answer much more).
'by' says to put letters next to each other.
'the met?' becomes 'opera' (I've seen this before).
'goer' after 'opera' is 'OPERA-GOER'.

I've seen this clue in The Times.
